Definitions

  • the present invention relates to a function expanding apparatus adapted to be connected with a portable compact electronic device, such as a laptop personal computer or word processor, thereby expanding the function of the electronic device.
  • a portable compact electronic device such as a laptop personal computer or word processor
  • a compact electronic device has predetermined functions. If it requires further functions, it is used with a function expanding apparatus which is designed to ensure those additional functions. This expanding apparatus adapted to be fitted with the electronic device so that signals can be transferred between the two.
  • the expanding apparatus and the electronic device are connected by means of a signal cable which is fitted with a plug-in connector on each end thereof. More specifically, they are connected by manually inserting a connector of the cable into that of the expanding apparatus or the electronic device.
  • an expanding apparatus is fixedly fitted with a plug-in connector and an insertion guide continuous therewith, and a connector attached to the rear portion of a compact electronic device is connected directly to the connector of the expanding apparatus by means of the insertion guide.
  • connection work In making connection according to the former arrangement, however, the connector of the signal cable must be grasped in hand, so that the connection work is troublesome. If the connectors have a large number of terminals, moreover, a great force is required to disconnect them manually from each other. Further, the connection or disconnection work requires a wide working space. When mounting the compact electronic device, which has the connector on its rear face, on the front portion of the expanding apparatus, therefore, it is difficult to secure the working space. Thus, this arrangement is not practical.
  • the latter arrangement for connection is used on the assumption that the position of the connector on the side of the electronic device relative to the connector of the expanding apparatus is fixed. Therefore, if this premise is not valid, that is, if the location of the connector of a electronic device is least deviated from that of the connector of the compact electronic device adapted for this arrangement, the connectors cannot be connected. Thus, the range of application of the expanding apparatus is limited.
  • An expansion apparatus for a personal computer is disclosed in US-A-4 769 764.
  • This known apparatus has a casing formed in an U-shaped configuration and the personal computer is inserted between the legs of the U-shaped casing and is supported on steps formed on the facing sides of the legs.
  • This known structure has the disadvantages that the connection between the expansion apparatus and the computer requires considerable manual force and the connectors are easily damaged as the force for insertion is imparted on the connectors via the computer. Further, as the computer is pushed into the mating connector of the expansion apparatus, the latter is liable to be displaced on the table where it is placed due to the fact that the insertion force is transmitted to the expansion apparatus so that the insertion operation is inconvenient.
  • the DE-U-8530786 relates to a capturing device for facilitating connection of a subminiature connector when the mating connector elements are displaced from their correct mounting positions and FR-A-1428377 discloses a connector arrangement for connecting multiple contact elements in which the contact elements are brought in contact with each other in that two plates containing the contact elements are connected in parallel and slidably relative parallel to each other. A lateral shift of the one plate parallel relative to the other is achieved by means of a lever.
  • This arrangement apparently is suitable only for establishing a firm electrical or mechanical contact between connector elements which are prearranged in such parallel plates and are provided with means allowing only the lateral shift of the one plate in parallel relative to the other.
  • the casing is fitted with a connector unit in a position to face the connector exposed to the rear face of the electronic device, which is positioned on the casing, in order to make the attachment and detachment of the compact electronic device easy and to reduce an impact given by the attachment or detachment work.
  • the unit includes a connector holder, which is fitted with a slider capable of reciprocating in the direction to approach and leave the connector on the side of the electronic device.
  • the holder is provided with an operating portion for moving the slider, and the slider is fitted with the apparatus-side connector which is adapted to be removably inserted into the device-side connector for connection.
  • the holder of the connector unit has fitting pieces on its lower surface which are adapted to removably engage the edge of a fitting portion in the casing, the fitting pieces being preferably formed of an elastic material.
  • the holding means is first drawn out forward for a suitable distance from the casing, and the electronic device is then mounted from above the casing.
  • the rear portion of the electronic device is placed on the bearing portion of the casing, and its front edge is engaged with the holding means.
  • the electronic device has its rear portion supported on the bearing portion, and is restrained from moving forward, i.e., in the direction to cause the connectors to be disengaged, by the holding means.
  • the electronic device can be mounted and held in position on the casing.
  • the holding means is movable in the depth direction with respect to the casing, its position can be aligned with the front edge portion of each of various types of compact electronic devices with different depths, whose rear portion is placed on the bearing portion, by adjusting the distance of the movement of the holding means.
  • various types of compact electronic devices can be mounted on the expanding apparatus.
  • the connector of the compact electronic device thus mounted on the casing is connected with the apparatus-side connector by plug-in connection. By doing this, signals are allowed to be transferred between the expanding apparatus and the electronic device.
  • the connector of the electronic device and the connector of the expanding apparatus are opposed to each other.
  • These two connectors are plug-in-connected to each other by moving the slider, with the apparatus-side connector thereon, toward the electronic device by means of the operating portion of the connector unit, using the connector holder as a guide.
  • the connected connectors can be disengaged from each other by moving the operating portion in the direction opposite to the moving direction for the connection.
  • the apparatus-side connector is drawn out from the device-side connector.
  • the electronic device need not be moved, so that high operating efficiency can be enjoyed, and the impact produced by the attachment or detachment work can be reduced.
  • the compact electronic device mounted on the expanding apparatus can be moved upward for the removal from the apparatus, it may possibly be lifted without disconnecting the two connectors from each other.
  • a disengaging force acts on the fitting pieces of the connector holder during the removal of the electronic device. If this force exceeds a predetermined level, the fitting pieces undergo elastic deformation to be disengaged from the edge of the fitting portion of the casing. In this manner, the connected connectors can be prevented from being subjected to an overload.
  • Fig. 2 shows a function expanding apparatus according to a first embodiment of the invention and a personal computer 1 for use as a compact electronic device to which the expanding apparatus is applied.
  • the computer 1 has a rectangular plane shape and is of the size A4. Generally, it is called a notebook- or book-type personal computer.

  • the front portion of the casing 12 serves as a supporting portion 21 which carries thereon the rear portion of the computer 1.
  • the cover 14 is stepped so that its front side is lower in level than its rear side, with respect to a step portion 14a.
  • the supporting portion 21 is defined by a top wall 21a on the front side and the step portion 14a.
  • the top wall 21a declines to the front side.
  • a positioning member 20 having a projection 22 in the shape of a truncated pyramid is provided on each side of the upper surface of the top wall 21a.
  • the distance C (see Fig. 2) between the respective roots of the paired projections 22 is substantially equal to the width A of the computer 1.
  • the positioning members 20 are used to restrain the crosswise movement of the rear portion of the computer 1, thereby positioning the computer 1 crosswise with respect to the expanding apparatus.
  • the step portion 14a abuts against the rear face of the computer 1 on the supporting portion 21, thereby restraining the rearward movement of the computer.
  • the members 20 and the step portion 14a constitute positioning means for positioning the rear portion of the computer 1 with respect to the expanding apparatus.
  • each positioning member 20 may be formed integrally with the cover 14, it is attached as an independent member to the cover 14 in the case of the present embodiment.
  • the member 20 is formed from a synthetic resin softer than the material of the cover 14.
  • Fig. 6 shows the way the member 20 is mounted on the top wall 21a.
  • Each member 20 is provided integrally with a receiving plate 23 which, adjoining the base of a positioning side face 22a of the projection 22, is adapted to carry the computer 1 thereon.
  • Hooks 24 protrude integrally from the receiving plate 23 and the lower end of the projection 22. These hooks 24 are inserted individually into slits 25 in the top wall 21a of the cover 14 so as to be caught by the edges of the slits.

  • the function expanding apparatus can be made applicable to compact electronic devices with different width-direction sizes A by mounting the positioning members 20 on the top wall 21a so that the distance C between the projections 22 can be adjusted.
  • the bottom of the casing 12 is formed flat, and four legs 27 are attached individually to the four corners of the bottom.
  • the bottom of the casing 12 is fitted with a rectangular plastic supporting plate 31, which can be drawn out forward from the casing in the direction of arrow D.

  • a pair of retaining portions 35 are formed on either side of the front edge of the supporting plate 31. Each portion 35 is formed by upwardly bending a flange integral with the plate 31. As mentioned later, these retaining portions 35 engage the front edge portion of the computer 1 on the supporting portion 21, thereby restraining the forward movement of the computer relative to the casing 12.
  • a rubber plate 36 is pasted on each retaining portion 35 and a front part of the supporting plate 31 continuous therewith.
  • a stopper mechanism 41 for restraining the movement of the supporting plate 31 is disposed in the casing 12. The following is a description of this mechanism 41.
  • the stopper mechanism 41 includes a metallic guide plate 42 which is located on the base 13 of the casing 12 so as to extend in the width direction thereof.
  • the guide plate 42 is formed having a horizontal portion 42a, which is screwed to the inside of the front portion of the base 13, and a vertical portion 42b rising upward from the front end of the portion 42a.
  • Placed on the upper surface of the horizontal portion 42a is an elongated metallic slider 43 which can slide in the longitudinal direction of the guide plate 42.
  • the slider 43 has a U-shaped cross section.
  • a slot 44 extending in the depth direction of the casing 12 is formed at the left-hand end portion (Fig.

  • the button 49 which is provided at one side wall of the base 13, can be pressed from the outside of the casing 12.
  • the movable shaft 49a causes the rocking lever 47 to rock in the direction of arrow F of Fig. 8.
  • the metallic slider 43 is moved in the direction of arrow G of Fig. 8 on the guide plate 42, against the urging force of the coil spring 45.
  • the slider 43 is restored to its original state (shown in Fig. 8) by means of the urging force of the spring 45.

  • a spring bearing plate 54 is mounted on and between the respective upper end portions of the paired guide shafts 51.
  • a leaf spring 55 is interposed between the bearing plate 54 and the upper surface of the stopper 50, and is welded to the plate 54.
  • numeral 56 denotes a retaining ring which is fixed to each guide shaft 51 to position the spring bearing plate 54. The spring 55 continually urges the stopper 50 downward.
  • a pair of cams 57 (only one of which is shown) are mounted on the metallic slider 43, corresponding to the stoppers 50.
  • the cam 57 which is made of synthetic resin, has a slanting cam surface 57a, as shown in Fig. 11. As the slider 43 reciprocates, the cam surface 57a approaches and leaves the cam follower 53 of the stopper 50, thereby moving the stopper up and down. When the surface 57a is disengaged from the follower 53, the stopper 50 is lowered by means of the urging force of the leaf spring 55.
  • each cam 57 has its flat surface 57b opposed to the cam follower 53.

  • a large number of engaging grooves 60 which are releasably engaged with the lower end portion of the projection 52, and one retaining groove 61 are formed on each side portion of the supporting plate 31 with respect to the width direction thereof.
  • the engaging grooves 60 are arranged at predetermined pitches P in the sliding direction D of the plate 31, and the profile of each groove 60 is identical with that of the lower part of the stopper projection 52.
  • a slanting surface 60a is formed on the front side of each engaging groove 60.
  • the retaining groove 61 which is designed in the same manner as each engaging groove 60, is located in front of the row of engaging grooves 60 at some distance from the front end thereof.
  • the stopper 50 When the supporting plate 31 is pushed in toward the casing 12 from the drawn-out state shown in Figs. 8 and 9, the stopper 50 is pushed up against the urging force of the leaf spring 55 by the action of the slanting surfaces 52a and 60a. Thus, the supporting plate 31 can be pushed in with ease. In contrast with this, the engagement between the stopper projections 52 and the engaging grooves 60 prevents the plate 31 from moving in the direction to be drawn out from the casing 12. Accordingly, the supporting plate 31 is prevented from being unexpectedly drawn out.
  • the release button 49 is depressed as the plate 31 is drawn out. When the button 49 is depressed, the metallic slider 43 slides in the direction of arrow G. Thereupon, each stopper 50 is pushed up by the slanting surface 57a of the cam 57, so that the stopper projections 52 are disengaged from the engaging grooves 60. As a result, the supporting plate 31 is allowed to be drawn out.
  • indexes 63 and 64 are provided near each row of engaging grooves 60 on the upper surface of the supporting plate 31. These indexes 63 and 64 are used as rough standards for the distance of draw-out of the plate 31 which depends on the depth B of each compact electronic device attached to the expanding apparatus 11.
  • the supporting plate 31 When the function expanding apparatus 11 is off duty, the supporting plate 31 is fully pushed in toward the casing 12, that is, into a retracted position where the plate 31 is concealed under the bottom of the casing 12, as shown in Fig. 4.
  • the projection 52 of each stopper 50 engages its corresponding retaining groove 61, thereby locking the supporting plate. In this manner, the housed supporting plate 31 is prevented from being carelessly pushed out forward.
  • two leaf springs 62 are screwed to the rear end portion of the bottom surface of the base 13.
  • the springs 62 When the supporting plate 31 is pushed into the retracted position, the springs 62 are pushed to be bent by the rear end edge of the plate 31, thereby producing an urging force to push out the plate 31 forward. If the release button 49 is depressed when the supporting plate 31 is drawn out, therefore, the springs 62 press the plate 31 forward, thereby reducing the force required for the draw-out of the plate 31.
  • the casing 12 is fitted with a connector unit 71 which is situated in a position to face the connector 6 of the computer 1 set on the supporting portion 21. Referring now to Figs. 12 to 23, this unit 71 will be described.

  • the distance Y from each pivot 78 as a fulcrum of the handle 76 to the extreme end (point of force) of the handle 76 is set longer than the distance X from the pivot 78 to the center (point of action) of each corresponding slot 79. Based on this relationship between the distances X and Y, the slider 74 can be subjected to a great moving force by rocking the handle 76 with a relatively small operating force.
  • the slider 74 supports a plug-in connector 81 having a large number of terminals 81a.
  • This connector 81 on the side of the expanding apparatus can be fitted into the computer-side connector 6 for connection.
  • the connector 81 is floatingly mounted on the slider 74.
  • leaf springs 82 and 83 are attached to the lower surface of the slider 74 and the bottom plate 72b of the connector holder 72, respectively, so that the connector 81 is elastically held between the extreme ends of the springs 82 and 83 in the vertical direction.
  • a tension spring 86 is stretched between a spring bearing portion 84, which is formed by bending the front portion of each end portion of the slider 74, and a spring bearing portion 85, which extends from the rear portion of its corresponding end portion of the connector 81.

  • Each pin 88 is pressed against the V-shaped corner portion of the hole 87 by the urging force of the tension springs 86.
  • a downward flange 89 is formed on the center of the rear portion of the slider 74.
  • the flange 89 which faces the central portion of the rear face of the connector 81, transmits the forward moving force of the slider 74 to the connector 81.
  • the connector 81 can be moved parallel without tilting when it is inserted into the connector 6. If the flange 89 is omitted, the rear edge of each angular hole 87 which is opposite to the V-shaped front edge can transmit the forward moving force of the slider 74 to the connector 81 by engaging its corresponding pin 88.
  • Guide pins 90 protrude forward from the opposite sides of the front portion of the connector 81, individually.
  • the respective tip end portions of the pins 90 which are tapered, are inserted individually into holes 91 (see Fig. 1) in a metal fixture for the connector 6.

  • the connector unit 71 is attached to the casing 12 of the expanding apparatus 11 by engaging the fitting hooks 94 with the fitting hole 18 (see Fig. 5) of the casing. In doing this, the hooks 94 are first aligned with the hole 18, and then pushed into the hole 18. Thereupon, the respective insert portions 94a of the fitting hooks 94 are inserted into the fitting hole 18 while undergoing elastic deformation. At the same time, the engaging recess portions 94b are elastically pressed against an edge 18a of the hole 18. Thus, the connector unit 71 is mounted on the casing 12. Naturally, in this mounted state, the base plate 93 and the shield cover 17 are connected electrically to each other by means of the fitting hooks 94, so that the connector unit can be electromagnetically shielded. Since the hooks 94 are elastically deformable, as described above, the connector unit 71 can be disengaged from the fitting hole 18 to be prevented from being damaged if it is subjected to an excessive drawing force by mistake.

  • the supporting plate 31 is drawn out forward from the casing 12. This is done while the release button 49 is being depressed. More specifically, when the button 49 is depressed, the rocking lever 47 is rocked in the direction of arrow F of Fig. 8, and at the same time, the shaft portion 48 in the slot 44 moves the metallic slider 43 in the direction of arrow G of Fig. 8 by pulling it. Thereupon, the cam surface 57a of the cam 57 raises each stopper 50 through the medium of the cam follower 53, so that the projection 52 of the stopper 50 is disengaged from the retaining groove 61. As a result, the supporting plate 31 is pushed out forward by the urging force of the leaf springs 62. Thereafter, a user pulls out the plate 31 forward along the guide plates 32, etc.
  • the distance of draw-out of the supporting plate 31 is suitably selected depending on the depth B of the compact electronic device to be connected. This selection is made with reference to the index 63 or 64.

  • the computer 1 is positioned in the width direction with respect to the casing 12.
  • the rear face of the computer 1 is caused to abut against the step portion 14a of the supporting portion 21, and the portion 14a restrains the computer from moving rearward.
  • the plate 31 If the retaining portions 35 of the supporting plate 31 are not in engagement with the front edge of the computer 1, in this state, the plate 31 is pushed in toward the casing 12 so that the portions 35 engage the front edge of the computer 1, and is locked to the retracted position by means of the stopper mechanism 41. Thus, the forward movement of the computer 1 is restrained by means of the pair of retaining portions 35. In consequence, the computer 1 is mounted in position on the casing 12, as shown in Fig. 3.
  • the top wall 21a of the supporting portion 21, which bears the rear portion of the computer 1 thereon, is situated higher in level than the supporting plate 31, and declines to the front side.

  • the slider 74 is pushed out forward along the guide slits 73 of the connector holder 72.
  • the connector 81 is also pushed out forward to reach its advanced position where it projects into the supporting portion 21.
  • the respective tip end portions of the guide pins 90 are inserted into their corresponding holes 91 of the connector 6 immediately before the connector 81 touches the connector 6.
  • the connector 81 can be accurately positioned with respect to the connector 6 through the guidance of the engagement between the pins 90 and the holes 91, even though the position of the connector 6 relative to the connector 81 is subject to some variation.
  • the movement of the connector 81 based on this guidance is allowed by the elastic deformation of the leaf springs 82 and 83 and the coil spring 86 which support the connector 81 floatingly.
  • the locking knob 99 of the unit 71 is moved in the direction of arrow H of Figs. 22 and 23, so that the one end portion 100a of the stopper plate 100 is inserted into the one guide slit 73.

  • the computer 1 can be removed from the expanding apparatus 11 by inversely following the aforementioned processes of mounting operation.
  • a disengaging force starts to be transmitted to the connector 81 through the engagement between the pins 88 of the connector 6 and the respective V-shaped edges of the angular holes 87 at the point of time when the edges abut against their corresponding pins 88 as the handle 76 is rocked rearward to retreat the slider 74.
  • the computer 1 can be removed upward from the expanding apparatus 11. Therefore, the computer 1 may possibly be lifted without disconnecting the connectors 6 and 81. In such a case, a great load acts on the fitting portion of the connector unit 71.
  • the unit 71 is attached to the casing 12 by elastically engaging the fitting hooks 94 on the lower surface of the base plate 93 with the edge 18a of the fitting hole 18 of the casing. If the disengaging force acts on the unit 71 as the computer 1 is lifted in the aforesaid manner, therefore, the hooks 94 undergo substantial elastic deformation to be disengaged from the edge 18a of the hole 18 when the force attains a predetermined level. As a result, the connector unit 71 is detached from the casing 12. Thus, the connected connectors 6 and 81 cannot be subjected to an overload, and can be prevented from being damaged.
  • the connector unit 71 has the cable protection cover 114 which is attached to the lower surface of the base plate 93, and the signal cable 95 extending from the connector 81 is led into the casing 12 through the inside of the cover 114 and the passage hole 116 in the cover 114.
  • the cover 114 can prevent the cable 95 from being caught in between the fitting hooks 93 and the edge 18a of the hole 18.
  • the cable 95 can be securely prevented from snapping.
  • the function expanding apparatus 11 has the following advantages.
  • the casing 12 is provided with the supporting portion 21 on which the rear portion of the compact electronic device 1 is placed, and the paired positioning members 20 for positioning the electronic device with respect to the width direction are provided at the portion 21.
  • the upward retaining portions 35 for retaining the front edge of the electronic device 1 are formed on the front portion of the plate 31. The position of each retaining portion 35 can be aligned with the front edge portion of each of various devices 1 with different depths, by adjusting the distance of draw-out of the supporting plate 31.
  • the forward movement of the compact electronic device 1, which causes the connector 6 to be disengaged from the apparatus-side connector 81, can be restrained, so that the connectors can be prevented from being unexpectedly disconnected from each other.
  • various types of compact electronic devices with different depths can be mounted on the expanding apparatus in a manner such that their movement in the width and depth directions is securely restrained.
  • a function expanding apparatus which can be fitted with various compact electronic devices, and enjoys a wide range of application.
  • the expanding apparatus can be made compact as a whole by concealing the supporting plate 31 under the bottom portion of the casing 12.
  • the connector unit 71 mounted on the casing 12 comprises the connector holder 72 and the slider 74, which is attached to the holder by means of the operating portion for reciprocation, and the connector 81 on the side of the expanding apparatus 11 is attached to the slider.
  • the connector 81 can be connected to or disconnected from the apparatus-side connector 6 by being reciprocated with respect to the compact electronic device on the expanding apparatus 11 by means of the operating portion.
  • the connectors 6 and 81 can be easily connected to or disconnected from each other without moving the whole electronic device or manually operating the connector 81 itself.

  • the connector 81 Since the connector 81 is floatingly supported by means of the leaf springs 82 and 83, it can freely shift its position in a desired direction after it is brought into contact with the connector 6 which is to be connected thereto. If the apparatus-side connector 6 is somewhat deviated vertically or crosswise with respect to the connector 81, or if the angle of the connector 6 is more or less shifted, the connector 81 can be smoothly aligned with the connector 6 due to the floating structure. Thus, the two connectors 6 and 81 can be securely connected to each other by plug-in connection, so that the expanding apparatus can be adapted for use with various compact electronic devices.
  • the connector unit 71 which has the elastic fitting hooks 94 protruding from the lower surface of the connector holder 72, is attached to the casing 12 by removably engaging the hooks 94 with the edge of the fitting hole 18 of the casing. If the compact electronic device 1 is lifted with the two connectors 6 and 81 connected with each other, therefore, the hooks 94 undergo elastic deformation to be disengaged from the hole 18 of the casing 12, so that the unit 71 is automatically removed from the casing, when the disengaging force acting on the hooks 94 exceeds a predetermined level. Thus, the connected connectors can be prevented from being subjected to an overload.
  • the operating portion for reciprocating the connector 81 to connect to or disconnect it from the connector 6 is not limited to the rocking handle 76, and may be formed of a handle fixed to the connector 81.
